Data refresh problem_SQL Server

Hey,

I have been facing issues while refreshing the dashboard since the past 3 weeks. Please help us in resolving the issue as we have to weekly refresh our dashboards.

Hi there

It would appear to me with the Mashup error would relate to the Power Query Engine.

I would suggest that you ensure that your On-Premise Data Gateway is running the latest version (July 2018)
And then download and install the latest version of Power BI Desktop (Aug 2018).

Then open the existing report in Power BI Desktop, then refresh the file. Once you have upgraded the On-Premise Data Gateway then upload the file and test the refresh.
